川东北地区线路铁塔岩石嵌固式基础应用浅析

Basis Application of Line Towers' Build-In Rock in Northeast Sichuan

四川盆地东北部地区,地形按地貌单元划分:主要为丘陵、低山～低中山。区内地层主要有第四系耕地层、残坡积粉质粘土层、冲洪积层(Q)、侏罗系(J)、白垩系(K)、三叠系(T)等砂岩～泥岩、灰岩,而以砂岩～泥岩、灰岩为主。线路铁塔岩石嵌固式基础在该区域内的大量应用,有不错的经济、环境、社会效益,同时,也是"资源节约型"、"环境友好型"—"两型三新"输电线路在工程实践中的具体应用。

Sichuan basin is in northeast Sichuan. The terrain could be classified into upland, low hill and middle low hill. According to the characteristic of the landscape, basis application of line towers＂ build-in rock has significant social, environmental and economic benefits. Simultaneously, the application of Power transmission line principle of ＂conservalion-oriented＂ ＂environment-friendly two types and three news＂ in construction practice are given.
